The methodology

PDA —
Persona Driven
Approach

The methodology behind all Babrun products.

The world changes.
People don't.

Every person carries a stable set of characteristics that form early in life and change slowly if at all. Not just physical ones like fingerprints — but complex ones that shape how you think, what you find effortless, what genuinely interests you, and how you prefer to engage with the world.

These characteristics are stable. And that stability is precisely what makes them useful as a foundation for any direction you choose.

In a world that shifts constantly — where careers disappear, industries transform, and the rules of success rewrite themselves every few years — the most reliable thing you have is who you are.

The question PDA is built to answer: how do you surface what is actually there?

You cannot find your real data
by thinking about it.

Most people have never decoded who they really are. This is not a character flaw. From childhood onward, other people's preferences, expectations, and assumptions are installed in place of self-knowledge — parents, education, employers, advertising, social norms.

By the time you are an adult, your conscious mind is full of borrowed material. When you ask it "what am I passionate about?" or "what are my real talents?" — it gives you what it has.

What it has is other people's answers. The introspective question cannot reach what is real. Reflection, journaling, exercises that ask you to think about yourself — all of them draw from the same compromised source.

PDA reads reactions, not beliefs.

Persona Driven Approach was developed by Fedir Nesterov — researcher, entrepreneur, coach, and founder of Babrun — based on years of working with people who were trying hard toward goals that were never really theirs.

Your real personal data is not in what you think. It is in how you react. When you respond to situations, choices, and questions — your genuine data leaves traces. Not what you believe about yourself. Not what you perform for others. What is actually there.

PDA records those traces and decodes them. Not what you think about yourself — what you actually carry.

Parameters of your real persona.

PDA decodes the characteristics that are most stable and most useful as a foundation for direction:

01

Passions

What genuinely pulls your attention — the domains and problems you return to without being told to.

02

Talents

What you do naturally and effortlessly, faster and more deeply than most people around you.

03

Character

How you actually engage with the world, how you make decisions, how you work, what you need.

+

And many others

Depending on what the specific product is designed to surface. These parameters are not invented or chosen. They are decoded. They were already there.
